Celestica Jumps 10% as AI Infrastructure Revenue Soars 83%
NEW YORK, October 27 —
Celestica Inc. (CLS) reported Q3 revenue up 83% year-over-year on AI infrastructure demand, sending shares 10% higher in after-hours trading.
- Q3 revenue up 83% YoY; both earnings and revenues topped analyst estimates
- At 12.6x forward earnings, the stock is priced like a legacy manufacturer despite growing at a hyperscaler supplier's pace
- Q4 revenue guidance and AI/HPS segment mix are the next proof points; watch both figures when the earnings call transcript drops
That rate in Q3 vs. 62.4% TTM: Growth Is Accelerating, Not Peaking
TTM revenue of $15.6bn reflects 62.4% YoY growth. Q3 printed that figure. The most recent quarter outpaced the trailing average by more than 20 points, which means the shift into AI infrastructure work is speeding up, not moderating. That is the signal the headline beat obscures.
A company growing faster at scale than it did at smaller scale is compressing the timeline to meaningfully larger revenue. Quarterly acceleration at $15bn in TTM sales is not what you expect from a manufacturing services firm; it is what you expect from a supplier with scarce, high-value capacity in a market where demand is running well ahead of supply.
12.6x Forward Earnings on a Company Implicitly Doubling EPS
At $246.65, CLS trades at 12.6x forward earnings against trailing EPS of $9.63. The forward multiple implies roughly a doubling of per-share earnings in the next twelve months, yet the market is still pricing the stock like a cyclical contract manufacturer at peak margins, not an AI infrastructure vendor with a documented acceleration in its core segment.
FCF of $729mn on $15.6bn in TTM revenue reinforces the argument: this is genuine cash conversion, not accounting leverage. The gap between what the growth rate implies and what the multiple prices in is where the opportunity sits, and it is unusually wide for a business of this quality.
The Only Real Bear Case Is One Input: Hyperscaler AI Capex
Celestica manufactures and assembles infrastructure for the companies building AI products; it does not build them itself. That means the bull case rests on a single input: hyperscaler AI capex remaining elevated. If major cloud platforms cut spending in response to a macro slowdown or AI monetization disappointment, HPS order volumes fall with it.
The number that proves the thesis wrong next quarter: any deceleration in AI/HPS segment revenue as a share of Q4 total. If the mix reverts toward lower-value contract work, the forward multiple reprices downward fast.
Q4 Guidance Is the Only Conversation Left
The Q3 beat is priced into the after-hours move. The real trade is whether Q4 guidance confirms that rate is a new floor rather than a high-water mark. Management commentary on HPS backlog depth and AI infrastructure order visibility is the single most important datapoint from this earnings cycle. Everything else is noise.
